is it normal not to ovulate?

I haven’t been on birth control for probably a year. I have normal periods and my ovulation (clear stringy discharge) is anywhere from day 14-16 in my cycle. Sometimes I’ve had it as late as day 18. But I just had my period July 13-19 and I haven’t had that clear stringy discharge yet. I’m starting to get concerned. I also have some abdominal pain on my right side and my right leg muscles are tight. Do any of you know if this is normal? Could I have just missed my ovulation discharge? I normally am able to track it and see it.
